How to test a web application for memory leaks?

Question

How to test a web application for the memory leaks?
How much does it contribute to the overall performance of the site?
Please suggest any tool which can help us test the web application for memory leaks.

Answer 1

Which platform are you developing on? This makes all of the difference in the world. A webapp done in Django/Python is going to test a lot differently than an ASP.NET site. You're better off searching for profiling tools based on the platform you're developing for.

Answer 2

对于php，您可以使用xdebug和kcachegrind。
